Magnetic monopole in the Feynman's derivation of Maxwell equations

In 1992, Dyson published Feynman's proof of the homogeneous Maxwell equatio ns assuming only the Newton's law of motion and the commutation relations b etween position and velocity for a nonrelativistic particle. Recently Tanim ura gave a generalization of this proof in a relativistic context. Using th e Hodge duality we extend his approach in order to derive the two groups of Maxwell equations with a magnetic monopole in flat and curved spaces. (C) 1999 American Institute of Physics.
